. Be it known that I, J OHNR. RICHARDSON, a citizen of, the-UnitedStates, residing at Madera; inthe county of Maderaand State ofCalifornia, have invented new and useful" Imprdvenien'ts inRoller-Bearings for-Axles,

-f which the followingis a specification.

- This invention relates to certain new and useful improvements in.roller -bearing for axles of vehicles, the object being toprovide asimple and .eifeetive roller' bearing, "by

diameter of the spindle and also of a greaterlengtlr than said spindle,the axlebox hav 'means of which the friction and wear of the parts willbe greatly reduced.

The invention consists'in the construction and combination of theparts,-in which'corn- .binatiou is included an .axleghaving formedthereon a collar from which projects a-cylin-i drical spindle, theeudgof the same being re?- duced and threaded to receive a not, an

axle-box the interior of which is cylindrical and of a greater diameterinteriorly than the ing one end bored outto receive the collarand'awasher which is held'thereby in the recess, a circular series of.rollers which are of less length than the :cylindrical portion of thespindle, which rollers have reduced or truncated ends, together with anut which has an annular portion for engagement with the shoulderf ofvthe spindle, and an exterior flange which retains in place a washer,the washer engaging withthe outer end of the axle-box, as will behereinafter set forth.

I have illustrated my invention bya side view, whichis partially brokenaway in order to show the proportion and configuration of the parts.

. Theaxle A has formed in egral therewith a collar a, having an annulai: periphery and a straight face or shoulder, froin'which thespindle Al projects, said spindle beingof the same diameter from thecollar (2 to a shoulder 1;, beyond which the spindle is reducedandprovided with threads b,with which the axle-nut engages.

The axle-box B has a cylindrical interior of greater diameter than thespindle, and the length of the cylindrical portion of theaxlebox fromits shoulder -c-to its outer and exceeds in' length the length ofthe-spindle, measuriugfro n the inner, face of the collar tion.

exitof the lubricant. q e 3 The nut-D is-of special construction, havarethe shoulder b. The ens-t ga. nettle Y sidetapers longitudinallyandis'provided with lugs or projections Bflwhich' hold thes me from-turningwhen driven intoa huh. T e sizeand shape of theexteriorof the axlelpo xare the same as-those iu gene'ral use,which permits the invention to bereadilyfapplied to the hubs of vehiclesjof ordinary construc- The inneror thicker end. of the axle-- boxis cutaway or' rea'med out" toreduceits thickness,=permitting the axle=boxtoextend over the collara, andprovides betweenthe collar of the spindle and the shoulder of v theaxle-box a spacewhich'reeeives'a washer d,

which washer and the -overlying portion of Abe axledaox willefiectively'prevent dust entering the bearing .and will also prevent theing a. thread which extends the: full depth of its recess, and the innerend of the niit abuts againstthe shoulder 12 of the spindle, while itsannular portion (1 is slightly less than the interior diameter of theasle-box, and its exterior' onannular flange d retains in place awasherwhich overlies the end of the axlebox. v i

The cylindrical space between the spindle andaxle-box is occupied by aseries of anti: I-

friction-rollers E, which rollers have their ends truncated and are ofless length than the cylindrical portion of the spindle. This admits oflongitudinal expansion of the n'oll- ,ere should the same becomeheatedin use and obviates binding or contact'of said roll- .ers with thecollar of the spindle or the inner face of the nut.

' By truncating the endsiof the rollers they may be readily insertedbetween the spindle and axle-box, and should they contact with the nutatone end or the washer or collar at the other-end suchoontact will notimpair the efliciency oi the device. For instance, con: tact with thewasher willonly be with one edge of thesame and contact with the annularportion-of. the-nut will be centrally upon its vinner face between thebox and spindle. This point oi contact obviates any tendency to expandthe nut-so that'it will jam in the box, and an expansion of the ends; ofthe rolls will not prevent the removalof the same, which would be thecase if they a collar, the other end being provided with a threadedportion of less diameter than the spindle, an axle-box which is ofgreater length than the length of the cylindrical portion of thespindle, said box being cut-out to provide a portion which receives thecollar of the spindle, 'a nut having an exterior flange d and an annularportion d which engages the spindle and the interior of the axlebox,washers one interposed between the axle-box and the collar of thespindle, and the other between the flange of the nut and the end of theaxle-box, and a circular series of rollers which are of loss length thanthe spindle, the rollers having truncated ends, substantially as shownand for the purpose set forth.

2. ln a roller-axle hearing, the combination of a spindle havingadjacent to" one end ,a

I collar, an axle-box having a cylindrical'intnrior and tapered ex.erior, lugs formed upon the outer side of the axle-box, the inner endof the axle-box being cut away to provide a recess of grca ter depththan the widthfof the collar on the spindle, a nut threaded forengagement with the outer end of the spindle and provided with a portiond which enters the axle-box and a flange d which overlies the outer endof the same; together with a circular series of rolls each roll havingits end reduced, said rolls being of less length than the length of thecylindrical portion of the spindle, substantially as'shown and for thepurpose set forth.

3. The combination with an axle having a collar a, a cylindrical spindleA, shoulder b, and threaded end beyond the shoulder, an axle-boxrecessed to receive the collar a of the spindle, the length of theunbroken cylindrical portion of the axle-box being more than theunbroken cylindrical portion of the spindle, of a nut having a flange dand 'a portion which entersthe end'of the axle box and engages shoulder12 on the spindle, washers between the collar of. the axle and theaxle-box and between the outer end of the axle-box and the flange d ofthe nut; together with cylindrical rolls the lengths of which arematerially less than the unbroken bearing-surface of the spindle,substantially as shown.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
